CANDLE-BURNING LANTERN FOR VEHICLES, 840.

SPECIFICATION forming part of Letters Patent No. 61 1,099, datedSeptember 20, 1898.

Application filed January 25, 1897. Serial No. 620,637. (No modal.)Patented in Austria November 29, 1896, No. 4,781/46.

T0 aZZ whom it may concern.-

Beit known that I, ALEXANDER BOOK, civil engineer, of Copenhagen, in theKingdom of Denmark, have invented certain'new and usef ul Improvementsin Candle-Burning Lanterns for Vehicles, &c. (for which I have obtainedLetters Patent in Austria, No. 4,7 81 +l6, dated November 29, 1896,) ofwhich the following is a specification.

The present invention relates to certain improvements in theconstruction of candleburninglanterns for vehicles and other means ofconveyance-such as carriage lanterns, ship-lanterns, bicycle-lanterns,&c.the special object in view with these improvements being to keep thecandle-cup dry, and thus avoid the drawbacks hitherto experienced withcandle-lanterns, such as a splashing, going out, &c.

The accompanying drawing shows a vertical section of such a lantern.

The lantern consists of two main parts viz., the lantern-space and thecandle-holder Bwhich two parts are connected together by means of apiece a, made of a heat-insulating material such as cork, wood, or asimilar substance. The heat of the lantern-space is thereby preventedfrom communicating itself through the walls of the lantern-space to thecandle-holder.

As there is no communication between the lantern-space and the outer airbelow the smoke-cap, the air that is necessary for the burning of thecandle is compelled to come from underneath and sweep along theinsulated candle-holder B. On account of the special construction ofthis candle-holder the air-current is directed as follows: Thecandle-holder is surrounded by a mantle 0, provided with holes Z2 ateach end and carrying a ring-formed plate D at the top. The uppersurface of this plate is shaped after a special curve that has beenfound out after numerous experiments, and the characteristic features ofthe shape of the plate D are as follows: The highest part of the plateisarranged at some distance from its inner edge, While the surface lyingbetween the highest part and the inner edge is bent downward toward thecup formed in the upper part of the candle around the wick in such amanner that the sectional curve of the plate-surface is approximatelyinone sweep with the sectional curve of the above-mentioned candle-cup.This shape causes the air-current, as shown by the arrows in thedrawing, after having passed around the candle-tube underneath the lowersurface of the plate D and its outer edge to sweep with increasingvelocity along the upper surface of the plate in such a manner that theair, being under the attractive influence of the suction produced in themiddle of the lantern by the flame, finally with great force is throwndownward in the candlecup toward the very root of the wick, whereafterit ascends into the flame.

Another special feature of the present invention is that the mantle C,that carries the plate D, is arranged so as to serve as a kind ofheat-conveyer. With this object in view the mantle C is made of a veryvoluminous heat-conducting material with a large cooling-surface,causing the heat to be given off downward to the atmosphere. The mantleC may suitably be made of thick copper. In order to increase the surfaceof the heat-conveyer, as also for the purpose of decoration, the lowerpart of the heat-conveyer may be cut up into strips G, that are rolledup in spirals or similar shapes, as shown on the drawing with dottedlines.

I claim- 1. A candle-burner having means for carrying the candle and forfeeding the same as it is burned, and provided with a plate having acentral orifice adapted to receive the burning end of the candle, theplate being curved upwardly from the outer edge and thence downwardly toform a continuation of the curve of the concavity which will exist atthe burning end of the candle, substantially as described.

2. A candle-burner having a chimney, a tube held at the lower end of thechimney and projecting downwardly therefrom, the tube being capable ofcarrying the candle, means for feeding the candle upwardly in the tube,and a plate located at the upper end of the tube and having a centralperforation adapted to receive the upper end of the candle, the platecurving from its outer edge upwardly and thence downwardlyso as to runinto the curve of the concavity at the upper end of the candle, theupper end of the tube having perforations through which all the air forsupporting combustion passes into the base of the chimney at the outeredge of the plate, substantially as described.

3. A candle-burner having a plate with an orifice therein, the upperface of the plate being curved inwardly and downwardly toward theorifice to form a continuation of the curve of the concavity which willexist at the burning end of the candle, substantially as described.

4. A candle-burner having a chimney, a mantle projected into the lowerend of the chimney, a block fitted between the upper end of the mantleand the lower end of the chimney, means within the mantle for holdingand feeding the candle upwardly into the 1; chimney, and a plate securedat the upper end of the mantle and having a perforation, the upper sideof the plate being curved downwardly toward the orifice so that saidcurve will run gradually into the curve of the concavity which willoccur at the upper end of the candle, substantially as described.

5. A candle lamp or lantern, provided with a disk having its upper faceconcaved at the center and its margin rounded or curved downwardly tothe lower face of the disk, and provided with a central aperture intowhich the end of a burning candle is adapted to project, the said diskbeing arranged with its .upper face above the openings through which allthe air for supporting combustion passes, substantially as described.

6. A candle lamp or lantern, comprising a candle-tube, a mantlesurrounding the candle-tube and provided with perforations at its upperend, through which perforations air for supporting combustion passes, adisk on the upper end of the mantle and having its upper face concave atthe center and its margin rounded or curved downwardly to the lower faceof the disk and provided wit-h a central aperture into which the burningend of the candle is adapted to project, and a chimneyinsulated from thesaid mantle, substantially as described.

7. A candle lamp or lantern, comprising a candle-tube, a mantlesurrounding the candle-tube and extending the length thereof, saidmantle being provided with perforations at its ends, through which airfor supporting combustion passes, a disk on the upper end of the mantleand having its upper face concave at the center and its margin roundedor curved downwardly to the lower face of the diskand provided with acentral aperture into which the burning end of the candle is adapted toproject, a chimney, and a ring of insulating material carried by thechimney between it and the mantle, substantially as herein shown anddescribed.

In testimony that I claim the foregoing as myinvention I have signed myname in presence of two subscribing witnesses.
